Mason Stains

Mason Stains are used both as an under glaze prior to the first firing, but can also be used after bisque for the second and final firing. When a stain is used prior to bisque, it is mixed with part of the clay body. It is then applied just like any under glaze. When it is used after bisque it is used with water only. These are two experimental bowls that were not acceptable for The Empty Bowls Project (mentioned in an earlier blog). I haven't found exact instructions and formulas about Mason Stains. I will be looking for this information before attempting this again. I bought this stain at Columbus Clay Company I look forward to using Mason Stains in the future as they give a very rich color that is hard to obtain with a glaze or even an under glaze.
